The projectile is propelled by a compressed gas propellant initially stored as a liquid in canister (10). The liquid is heated to a super critical state in chamber (8) by heating element (12) to induce a phase change such that the liquid becomes a highly dense gas. The phase change from liquid to gas provides the energy required to expel the projectile at high velocity from rifle (1), regardless of the ambient temperature.
The propellant is preferably CO2 which is heated to 31.06 °°C.
Rifle (1) produces minimal noise and no heat signature, making it suitable for military and stealth purposes. A pistol and launchers for grenades or mortar bombs are also disclosed. Another version can launch low earth orbit satellites or payloads.

Description
PROJECTILE FIRING DEVICE USING LIQUIFIED GAS PROPELLANT
TECHNICAL FIELD
The present invention relates to a projectile firing device, and more particularly to such a device that uses a propellant that is initially stored in a liquid phase and undergoes a phase change to a "highly dense" gas to effect propulsion of the projectile.
The projectile firing device may in number of embodiments relate to a weapon such as a gun, rifle, pistol, grenade or mortar launcher. In another embodiment the projectile firing device may be used as a low earth orbit satellite-launch device.
BACKGROUND
Conventional weapons such as rifles and guns use gunpowder or cordite as the explosive material to propel ammunition. Such explosive materials provide a violent expansion of gases and the liberation of relatively large amounts of thermal energy to achieve propulsion of the ammunition. There are a number of disadvantages associated with such conventional weapons. Firstly, they are highly inefficient in energy transferral from the explosive material to the projectile velocity of the ammunition. In many instances only 20-40% of the energy released by the exploding material is transferred to the projectile velocity.
A number of other disadvantages associated with conventional guns arid rifles are the emission of large amounts of thermal energy (heat) and noise that can be easily detected with and without the aid of conventional detection equipment. Also, due to the large amounts of thermal energy being released the barrel and breech of a conventional gun or rifle must be able to withstand high temperatures arid therefore are typically made of steel.
There are known guns that utilise a compressed gas, such as carbon dioxide (COQ) to effect propulsion of a projectile. Such arrangements use C02 in a gaseous state stored in a canister that is removably attached to the gun. Known guns that use such an arrangement are spear guns and paintball guns. However, such arrangements are not suitable for high velocity weapons of the type used for military purposes.
Attempts have been made in the past to heat the gas propellant of gas powered projectile firing devices. US Patent No. 5,462,042 (Greenwell) describes a COa powered paint ball gun in which CO~ is initially stored in a conventional C02 cartridge. The initial expansion of the chilled C02 occurs in an expansion chamber in the form of a passage which passes through the hand grip l6 and may be warmed by the heat of a user's hand.
This arrangement is to speed up the heating of the C02 prior to firing of the gun.
German Patent Application DE 3733-240 (Steyr-Daimler-Punch AG) describes a gun to using a liquefied gas propellant. The gun has a heater fox heating gas as it passes through a tube towards the propellant chamber. The gas is heated on its way to the propellant chamber to enhance precision of the gun by compensating for temperature changes which affect the liquid-gas propellant.
The above described prior art guns utilise heating arrangements that provide heat to the propellant gas prior to it reaching the propellant chamber, in an attempt to overcome firing problems that may occur at colder ambient temperatures. However, these heating arrangements suffer from the disadvantage that they do not ensure reliable repeated firing of a gun over a wide range of cold ambient temperatures.
The present invention seeks to provide a projectile firing device that overcomes the 2o disadvantages associated with conventional weapons and with known gas powered projectile firing devices as described above. It also seeks to provide a means for other projectile firing applications such as launching low earth orbit satellites and payloads.
According to a first aspect the present invention is a projectile firing device comprising:
an elongate barrel through which a projectile is fired;
loading means for introducing said projectile into said barrel;
said projectile being adapted to be propelled by a compressed gas propellant, characterised in that said compressed gas propellant is initially stored as liquid and adapted to be heated by a heating means which induces a phase change such that said propellant becomes a highly dense gas.
Preferably in one embodiment said device comprises at least one chamber for holding said compressed gas propellant, said chamber being in fluid communication with said barrel via a valve means adapted to release said compressed gas propellant to fire said projectile held in said barrel, and a reservoir located remote from said chamber for storing said propellant in its initial liquid state, and a means for introducing said to propellant in its liquid state from said reservoir into said chamber.
Preferably said device is a weapon, such as a rifle, gun or pistol. Preferably said barrel of said weapon is made of a composite material such as kevlar/aluminiurn laminate and metals such as steel, arid said barxel has a teflon coated bore. Preferably where said device is a rifle it has a body, stock and pistol grip made of plastic, such glass filled nylon.
Alternatively, said device is a satellite-launch device and said projectile is a low earth orbit satellite. Preferably said satellite-launch device comprises a plurality of modular units and a plurality of chambers. Preferably each chamber is associated with at least one modular unit.
2o A projectile firing device as described in any of the abovementioned embodiments wherein said device further comprises an electronic control unit, which controls the ingress of the propellant in its liquid state from the reservoir to said chamber and controls the heating means used to heat said propellant. Preferably where said projectile firing device is a weapon or satellite launching device it further comprises targeting means for targeting said projectile and said electronic control unit is operably connected to said targeting means to control ingress of said propellant to said chamber and to control the heating means used to heat said propellant in response to varying targeting parameters.
In another embodiment of said projectile firing device, said projectile is housed within a cartridge, said cartridge containing a reservoir of propellant in its initial liquid state and a thermal detonator adjacent thereto, said heating means adapted to heat said thermal detonator which in turn heats propellant. Preferably said device is a weapon, such as a grenade launcher.
In a further embodiment of said device, said projectile is housed within a cartridge, said cartridge containing a reservoir of propellant in its initial liquid state and at least a portion of said heating means adapted to heat said propellant is integral with said cartridge. Preferably said cartridge uses a portion of the explosive energy of the propellant to continue acceleration of the projectile for a period of time after the projectile has left said device. Preferably said device is a weapon, such as a mortar to launcher.
A projectile firing device as defined in any of the abovementioned embodiments wherein said device further comprises an electronic control unit, which controls the ingress of the propellant in its liquid state from the reservoir to said chamber and controls the heating means used to heat said propellant.

MODE OF CARRYING OUT INVENTION
2o Figures 1 to 4 depicts a rifle 1 and its ammunition in accordance with a first embodiment of a projectile fixing device of the present invention. In a similar manner to conventional rifles, rifle 1 has a rifled barrel 2, stock 3, breech 4, pistol grip 5, trigger mechanism 6 and removable ammunition magazine 7.
Rifle 1 also has a high-pressure chamber 8 in fluid communication with barrel
2, via a gas lock off-valve 9. A canister 10 containing liquid carbon dioxide (C02) is integrally housed within magazine 7.
The rifle 1 fires an ammunition projectilell loaded into breech 4 in the following manner. The liquid COZ contained in canister 10 is the propellant used to fire projectile 11. Liquid C02 is introduced into chamber 8 from canister 10. The fluid communication means between canister 10 and chamber 8 has been omitted from the figures for the purpose of clarity. The liquid C02 in chamber 8 is heated by a heating element 12 that is powered by an electrical battery power supply 14 housed within pistol grip 5.
1o When C02 is heated to 31.06°C, it changes to a "super critical state" which is a "highly dense" gas at high pressure. In this embodiment the critical state of C02 as it changes phase from liquid to a gas, provides the explosive energy required to expel projectile 11 at high velocity from rifle 1, regardless of the ambient temperature. This explosive process which fires projectile 11, occurs with minimal noise and no heat signature emitting from rifle 1, thereby making rifle 1 advantageous when used for military and stealth purposes.
The following table depicts the temperature/pressure relationship of Liquid/gas C02.
Temperature (°C) Pressure (bar) 31 74 Critical point The suitability of CO2 as a preferred propellant can be appreciated by the following:
~ 1 gram of liquid CO2 will liberate to 500cc of gas at 25°C
~ 1 gram of CO~ = 0.759cc at 25°C
~ 1cc of liquid COZ will liberate to 660cc at 25°C
In use rifle 1, operates as follows with reference to Figures 5-8. A pneumatic loading mechanism 15 is used to load a projectile 11 contained in magazine 7 into breech 4.
When breech 4 is lowered into the loading position as shown in figure 6, the targeting system sight module 16 and of a laser sight generator 13 is activated and reflected up barrel 2.
An electronic module or electronic control unit (ECU) 17 is operably connected to sight module 16 and a Global Positioning System (GPS) as well as operably connected to the CO~ supply and chamber 8. ECU 17 adjusts and monitors targeting, COZ supply and 1o pressures to match the COZ requirements to that of the distance of the target. In addition the ECU 17 is operably connected to other components within xifle 1 and may control and monitor electric power supply, projectiles and possible communication systems integrated within the rifle.
When a target is acquired by the user of rifle 1, through sight module 16, GPS
and targeting information is in view to the user of the rifle 1 via a heads up display within sight module 16. Adjustment of laser positioning and prism angles for target acquisition occurs instantaneously, and target information may preferably be electronically processed via processing devices used for focussing and triangulation of known electronic video or still cameras.
2o As the targeting system is operational, a metered amount of liquid CO~, say for example 5ce, is allowed to enter chamber 8. A small current is passed through heating element 12. The heating of the liquid C02 results in its pressure building up in a fxaction of a second.
When trigger mechanism 6 is pulled, breech 4 returns to the firing position as shown in Figure 7. Gas lock-off valve 9 activates the COZ at the critical state at which it is a highly dense gas arid projectile 8 is dispatched at high velocity as shown in Figure 8.
Preferably as projectile 11 is forced up the bore of barrel 2, the rear of projectile is adapted to flare, to promote a good gas seal. The flaring action promotes a rotational motion from the rifling of barrel 2. Preferably both the barrel 2 and projectile 11 are coated with Teflon to minimize bore wear. Driving bands may also be incorporated to assist spin on projectile 11.
As projectile 11 leaves rifle 1, residual pressure is used to reposition breech 4 to the reload position. The loading mechanism is reactivated and rifle 1 will then regain the target acquisition mode.
Preferably the rifle 1, can be used in a single shot mode, or an automatic mode when the trigger mechanism 6 is left in the fire position.
It should be understood that the various components of rifle 1 can be manufactured from lighter materials than those of conventional rifles, as the explosive release of 1o energy of the C02 propellant in rifle 1 is more efficient, and therefore a number of the various components of rifle 1 do not have to be of the same material and heat resistant properties as that required in conventional high velocity rifles. For instance the chamber 8 may preferably be manufactured in titanium, stainless steel or aluminium to reduce bulk and to contend with extreme pressures, whilst the major part of the body 15 including stock 3 and pistol grip 5 may preferably be manufactured from injection moulded glass filled nylon. Preferably the barrel 2 is made from an aluminium/kevlar laminate material with the bore of barrel 2 being coated with teflon and/or chrome-steel.
In addition to the CO~ canister 10 and the battery pack power supply 14, rifle 1 is also equipped with auxiliary C02 charges 10a and a backup battery pack power supply 14a 2o contained within stock 3, as shown in Figure 1.
Preferably breech 4 is an electromagnetic/pneurnatic arrangement, with a mechanical override. The breech 4 may be manufactured from alurninium/kevlar laminate with a teflon coated bore.
The projectiles 11 which are fired from rifle 1 are preferably manufactured with a tip 25 and central core of tungsten. The rear and outer body is made of kevlar, which is coated with teflon or teflon impregnated with carbon. The rear of the projectile is designed to flare and expand under high pressure to ensure a good gas seal, which also promotes projectile rotational motion, from the internal rifling of the bore of barrel 2.
It should be understood that rifle 1 as disclosed above may also be provided with conventional attachment points for a bayonet and hand grenade launcher and sling.
Figures 9 and 10 depict a pistol 21 in accordance with a second embodiment of a projectile firing device of the present invention. The pistol 21 like the rifle 1 fires an 5 ammunition projectile 11 loaded into breech 4. In particular, pistol 21 also contains a liquid COZ canister 10 that is loaded into the pistol grip 25 along with magazine 7 containing projectiles 11. In a like manner to that of rifle 1, liquid C02 contained within canister 10 is introduced into chamber 8 and may be heated by a heating element 12 that is powered by an electrical battery power supply 14 housed within the body of l0 pistol 21. The dispatch of projectiles 11 occurs in a similar manner to that in rifle 1 in that the liquid C02 is induced to change its state fxom a liquid to a "highly dense" gas.
Figure 11 depicts an artillery/naval gun 31 in accordance with a third embodiment of a projectile firing device of the present invention. The gun 31, like that of rifle 1 of the first embodiment utilises liquid C02 which is introduced into a chamber 8 and then heated to ensure a phase change to a "highly dense" gas. In addition to the primary chamber 8, the gun 31 may also be provided with secondary chambers 8a and 8b that are also loaded with liquid COZ. As a projectile dispatched by the explosive charge of CO~ from the primary chamber 8 passes sensors 17A and 17B associated respectively with secondary chambers 8a and 8b, gas within those chambers is also released assisting 2o im the dispatch of the projectile. Gun 31 may preferably have a barrel of approximately two metres in length. The firing of the primary chamber 8 followed by assistance to the projectile 11 via secondary chambers 8a and 8b is able to provide a higher velocity to the projectile 11 than would be achieved with a single chamber 8. As with rifle 1 of the first embodiment it is envisaged that a kevlar/aluminium composite could be used, thereby making the gun 31 up to five times the strength of steel fox a given weight.
Figures 12-15 depict a grenade launcher 41 and ammunition fitted to rifle 1 of the first embodiment in accordance with a fourth embodiment of a projectile firing device of the present invention. In this embodiment the grenade launcher 41 is for launching grenade cartridges 11a each of which comprise a fore compartment 42, and aft compartment 43 3o and a central compartment 44 therebetween. The fore compartment 42 contains a detonator 45 and high explosive 46, the central compartment 44 contains a charge of liquid C02, and aft compartment 43 cornpxises of a magnesium compound thermal detonator. The fore compartment 42 is adapted to readily separate from central compartment 44.
In this embodiment the grenade launcher 41 utilises a heating element (not shown) operably connected to electrical battery power supply 14 or 14a of rifle 1, which is activated by trigger mechanism 6. The heating element is used to heat the aft compartment (magnesium compound thermal detonator) 43 of a grenade cartridge 11a in the loaded position. The heat generated by the magnesium compound thermal detonator is sufficient to ensure that the liquid C02 undergoes a phase change to a to "highly dense" gas, thereby providing explosive energy that destructs central compartment 44 and separates fore compartment 42 therefrom, and expelling the fore compartment 42 containing detonator 45 and high explosive 46 as a projectile from grenade launcher 41 via its barrel 2a. The grenades cartridges 11a are carried by a carousel-magazine 47.
Figure 16 to 23, depict a mortar launcher 51 and mortar projectiles 11c in accordance with a fifth embodiment of a projectile firing device of the present invention. The mortax launcher 51 may typically be constructed of an aluminium/kevlar composite and comprise a high energy output battery pack 14b, electronic inclinometer, GPS
and compass display 16b for accurate targeting, and a lightweight adjustable stand 52. Up to 70% weight saving can be achieved by using the aluminium/kevlar composite materials to provide infantry with a more mobile mortar suppoxt facility. The tubular body of launcher 51 has an aluminium honeycomb central section 63 "sandwiched" between an inner I~evlar section 64 and an outer Kevlar section 62.
The mortar projectile 11c is a high explosive pre-shrapnel projectile comprising a front section 53 and a rear section 54. The front section 53 may be manufactured from steel containing high explosive 55 surrounded by pre-fragmented steel particles 56 (which can be replaced by magnesium composite to produce an incendiary device) and a detonator 57. The detonator 57 can be adjusted with a pre-set timer to detonate in-flight or upon impact.
3o The rear section 54, which may also be manufactured from steel, contains liquid CO2.
This rear section also houses a magnesium-oxide composite with a soft metal failure diaphragm 58 and four stability fins 59 with copper tipped electrodes.
Surrounding the front and rear sections 53 and 54 are two nylon collar bands, coated with teflon or teflon impregnated with carbon.
The mortar launcher 51 typically set up and levelled by the use of adjustable support legs of stand 52. Angle of incline and positioning, adjusted by use of front support 52a, by the user referring to electronic inclinometer, GPS and compass display 16b mounted on the barrel. A laptop or hand-held computer could be used in conjunction with GPS
and a Terrain Mapping program to calculate and pinpoint accuracy, and would be advantageous for "Terrain Impaired" hidden targets.
The projectile 11c is dropped into the top of the barxel 2c of launcher 52 and falls to its base. The fins 59 of projectile 11c, equipped with copper tipped electrodes 60, strike the electrode segments 61 situated at the base of launcher 51, making an electrical circuit as the electrode segments are operably connected to battery pack 14b.
This ignites the magnesium-oxide composite (magnesium burns at 650°C), superheating the liquid COZ making a supercritical substance (highly dense gas) at very high pressure.
At a pre-determined pressure, e.g. about 1350 bar, the soft metal diaphragm 58 fails. So as not to contaminate the base of launcher 51, the diaphragm 58 has a steel cable connected to it so it stays with the projectile.
A rapid rise in pressure takes place flaring the nylon collar bands to promote a good gas seal and to prevent a metal-to-bore contact. The projectile 11c is expelled.
As projectile 11c leaves the bore of launcher 51, approximately 50% of the supercritical C02 has been utilised. The remainder now acts as the propellant, further accelerating the projectile.
The estimated projectile cycle time for launcher 51 is 4 seconds.
An ammunition box of approximately twenty projectiles 11c would also hold a spare high output battery pack 14b. One fully charged battery 14b would preferably be sufficient to expel 100 projectiles.
The projectile firing device of the present invention can also be used to launch commercial and military satellites or payloads at low cost into low earth orbit (LEO).
Prior technologies have previously produced a launching system to put satellites into LEO. One system has launched a probe to an altitude of 180krn and another system has not bettexed this result.
When a satellite circles close to the earth it is known as low earth orbit (LEO). Satellites in LEO are 320-800km (200-500 miles) high and circle the earth in approximately 90 minutes at a speed of 24, 360kph (17,OOOmph).
To launch a LEO satellite the projectile needs to attain a velocity of 7920 metres per second (5 miles per second) when leaving the barrel or launch tube. The projectile firing device of the present invention can achieve this by accelerating a projectile in a rapid sequence by employing a number of independent liquid to gas C02 chambers in a chain reaction.
Figures 24-27 depict a satellite-launch device 70 for launching a LEO
projectile 79 into a low earth orbit in a sixth embodiment of a projectile firing device of the present invention. Launcher 70 comprises a plurality of modular units 71, typically eight or more such units. In this preferred embodiment, eight modular units each of about eight metres in length are used. Each unit 71 comprises a CO2 vessel 72, heating element 73, explosive activated burst disc 74, a smooth barrel bore 75, an electronic projectile location sensor 76 and an electronic control unit (ECU) 77.
Each high pressure C02 vessel 72 contains a metered amount of liquid CO2. A
heating element 73 is incorporated to heat the liquid CO~ to a pressure in excess of 4000 bar. Its associated burst disc 74 is attached, sealing the pressure vessel from the bore 75. The burst disc 74 has a fault machined into it; the fault is filled with a shaped high explosive charge to enable an extremely rapid release of the highly dense gasified and super-heated C02.
A bore 75 of each modular unit 71 is smooth to reduce friction. Electronic sensors 76 are located within the launcher bore 75 to detect and monitor a projectile 79 within the launcher 70. The ECU 77 is used monitor and control the launch of a projectile 79.
In use a LEO projectile 79, which in this embodiment is about four metres in length and about one metre in diameter, is placed into breech 80 at one end of launcher 70, and then breech 80 is then sealed. Projectile 79 is carried by a carrier 82, having a plurality of low friction bands 83. All pressure vessels 72 are then charged with liquid C02 with burst discs 74 in place. The liquid COZ is heated until the required pressure is obtained to induce a phase change to "highly dense" gas . The pressure vessel 72 closest to breech 80 is then released which pushes the projectile 79 up the bore at high velocity.
The projectile 79 is sensed by sensors) 76 in the second adjacent modular unit 71 arid then the second stage is activated releasing CO~ in the next stage. As projectile 79 is moving through the bore 75 so fast, a very quick response mechanism is required to release the high pressure C02. A C-shaped explosive charge 81 is required to fracture the burst disc 74 and release the CO2 gas at high volume and high speed. The process is a very rapid deployment of projectile 79 from launcher 70.
It should be understood that whilst C02 has been selected as the preferable propellant due to its properties and commercial availability, other liquid/gaseous propellants could be used in alternative embodiments.
The term "comprising" as used herein is used in the inclusive sense of "including" or "having" and not in the exclusive sense of "consisting only of '.
The rifle 1 fires an ammunition projectilell loaded into breech 4 in the following manner. The liquid COZ contained in canister 10 is the propellant used to fire projectile 11. Liquid C02 is introduced into chamber 8 from canister 10. The fluid communication means between canister 10 and chamber 8 has been omitted from the figures for the purpose of clarity. The liquid C02 in chamber 8 is heated by a heating element 12 that is powered by an electrical battery power supply 14 housed within pistol grip 5.
1o When C02 is heated to 31.06°C, it changes to a "super critical state" which is a "highly dense" gas at high pressure. In this embodiment the critical state of C02 as it changes phase from liquid to a gas, provides the explosive energy required to expel projectile 11 at high velocity from rifle 1, regardless of the ambient temperature. This explosive process which fires projectile 11, occurs with minimal noise and no heat signature emitting from rifle 1, thereby making rifle 1 advantageous when used for military and stealth purposes.
The following table depicts the temperature/pressure relationship of Liquid/gas C02.
Temperature (°C) Pressure (bar) 31 74 Critical point The suitability of CO2 as a preferred propellant can be appreciated by the following:
~ 1 gram of liquid CO2 will liberate to 500cc of gas at 25°C
~ 1 gram of CO~ = 0.759cc at 25°C
~ 1cc of liquid COZ will liberate to 660cc at 25°C
In use rifle 1, operates as follows with reference to Figures 5-8. A pneumatic loading mechanism 15 is used to load a projectile 11 contained in magazine 7 into breech 4.
When breech 4 is lowered into the loading position as shown in figure 6, the targeting system sight module 16 and of a laser sight generator 13 is activated and reflected up barrel 2.
An electronic module or electronic control unit (ECU) 17 is operably connected to sight module 16 and a Global Positioning System (GPS) as well as operably connected to the CO~ supply and chamber 8. ECU 17 adjusts and monitors targeting, COZ supply and 1o pressures to match the COZ requirements to that of the distance of the target. In addition the ECU 17 is operably connected to other components within xifle 1 and may control and monitor electric power supply, projectiles and possible communication systems integrated within the rifle.
When a target is acquired by the user of rifle 1, through sight module 16, GPS
and targeting information is in view to the user of the rifle 1 via a heads up display within sight module 16. Adjustment of laser positioning and prism angles for target acquisition occurs instantaneously, and target information may preferably be electronically processed via processing devices used for focussing and triangulation of known electronic video or still cameras.
2o As the targeting system is operational, a metered amount of liquid CO~, say for example 5ce, is allowed to enter chamber 8. A small current is passed through heating element 12. The heating of the liquid C02 results in its pressure building up in a fxaction of a second.
When trigger mechanism 6 is pulled, breech 4 returns to the firing position as shown in Figure 7. Gas lock-off valve 9 activates the COZ at the critical state at which it is a highly dense gas arid projectile 8 is dispatched at high velocity as shown in Figure 8.
Preferably as projectile 11 is forced up the bore of barrel 2, the rear of projectile is adapted to flare, to promote a good gas seal. The flaring action promotes a rotational motion from the rifling of barrel 2. Preferably both the barrel 2 and projectile 11 are coated with Teflon to minimize bore wear. Driving bands may also be incorporated to assist spin on projectile 11.
As projectile 11 leaves rifle 1, residual pressure is used to reposition breech 4 to the reload position. The loading mechanism is reactivated and rifle 1 will then regain the target acquisition mode.
Preferably the rifle 1, can be used in a single shot mode, or an automatic mode when the trigger mechanism 6 is left in the fire position.
It should be understood that the various components of rifle 1 can be manufactured from lighter materials than those of conventional rifles, as the explosive release of 1o energy of the C02 propellant in rifle 1 is more efficient, and therefore a number of the various components of rifle 1 do not have to be of the same material and heat resistant properties as that required in conventional high velocity rifles. For instance the chamber 8 may preferably be manufactured in titanium, stainless steel or aluminium to reduce bulk and to contend with extreme pressures, whilst the major part of the body 15 including stock 3 and pistol grip 5 may preferably be manufactured from injection moulded glass filled nylon. Preferably the barrel 2 is made from an aluminium/kevlar laminate material with the bore of barrel 2 being coated with teflon and/or chrome-steel.
In addition to the CO~ canister 10 and the battery pack power supply 14, rifle 1 is also equipped with auxiliary C02 charges 10a and a backup battery pack power supply 14a 2o contained within stock 3, as shown in Figure 1.
Preferably breech 4 is an electromagnetic/pneurnatic arrangement, with a mechanical override. The breech 4 may be manufactured from alurninium/kevlar laminate with a teflon coated bore.
The projectiles 11 which are fired from rifle 1 are preferably manufactured with a tip 25 and central core of tungsten. The rear and outer body is made of kevlar, which is coated with teflon or teflon impregnated with carbon. The rear of the projectile is designed to flare and expand under high pressure to ensure a good gas seal, which also promotes projectile rotational motion, from the internal rifling of the bore of barrel 2.
It should be understood that rifle 1 as disclosed above may also be provided with conventional attachment points for a bayonet and hand grenade launcher and sling.
Figures 9 and 10 depict a pistol 21 in accordance with a second embodiment of a projectile firing device of the present invention. The pistol 21 like the rifle 1 fires an 5 ammunition projectile 11 loaded into breech 4. In particular, pistol 21 also contains a liquid COZ canister 10 that is loaded into the pistol grip 25 along with magazine 7 containing projectiles 11. In a like manner to that of rifle 1, liquid C02 contained within canister 10 is introduced into chamber 8 and may be heated by a heating element 12 that is powered by an electrical battery power supply 14 housed within the body of l0 pistol 21. The dispatch of projectiles 11 occurs in a similar manner to that in rifle 1 in that the liquid C02 is induced to change its state fxom a liquid to a "highly dense" gas.
Figure 11 depicts an artillery/naval gun 31 in accordance with a third embodiment of a projectile firing device of the present invention. The gun 31, like that of rifle 1 of the first embodiment utilises liquid C02 which is introduced into a chamber 8 and then heated to ensure a phase change to a "highly dense" gas. In addition to the primary chamber 8, the gun 31 may also be provided with secondary chambers 8a and 8b that are also loaded with liquid COZ. As a projectile dispatched by the explosive charge of CO~ from the primary chamber 8 passes sensors 17A and 17B associated respectively with secondary chambers 8a and 8b, gas within those chambers is also released assisting 2o im the dispatch of the projectile. Gun 31 may preferably have a barrel of approximately two metres in length. The firing of the primary chamber 8 followed by assistance to the projectile 11 via secondary chambers 8a and 8b is able to provide a higher velocity to the projectile 11 than would be achieved with a single chamber 8. As with rifle 1 of the first embodiment it is envisaged that a kevlar/aluminium composite could be used, thereby making the gun 31 up to five times the strength of steel fox a given weight.
Figures 12-15 depict a grenade launcher 41 and ammunition fitted to rifle 1 of the first embodiment in accordance with a fourth embodiment of a projectile firing device of the present invention. In this embodiment the grenade launcher 41 is for launching grenade cartridges 11a each of which comprise a fore compartment 42, and aft compartment 43 3o and a central compartment 44 therebetween. The fore compartment 42 contains a detonator 45 and high explosive 46, the central compartment 44 contains a charge of liquid C02, and aft compartment 43 cornpxises of a magnesium compound thermal detonator. The fore compartment 42 is adapted to readily separate from central compartment 44.
In this embodiment the grenade launcher 41 utilises a heating element (not shown) operably connected to electrical battery power supply 14 or 14a of rifle 1, which is activated by trigger mechanism 6. The heating element is used to heat the aft compartment (magnesium compound thermal detonator) 43 of a grenade cartridge 11a in the loaded position. The heat generated by the magnesium compound thermal detonator is sufficient to ensure that the liquid C02 undergoes a phase change to a to "highly dense" gas, thereby providing explosive energy that destructs central compartment 44 and separates fore compartment 42 therefrom, and expelling the fore compartment 42 containing detonator 45 and high explosive 46 as a projectile from grenade launcher 41 via its barrel 2a. The grenades cartridges 11a are carried by a carousel-magazine 47.
Figure 16 to 23, depict a mortar launcher 51 and mortar projectiles 11c in accordance with a fifth embodiment of a projectile firing device of the present invention. The mortax launcher 51 may typically be constructed of an aluminium/kevlar composite and comprise a high energy output battery pack 14b, electronic inclinometer, GPS
and compass display 16b for accurate targeting, and a lightweight adjustable stand 52. Up to 70% weight saving can be achieved by using the aluminium/kevlar composite materials to provide infantry with a more mobile mortar suppoxt facility. The tubular body of launcher 51 has an aluminium honeycomb central section 63 "sandwiched" between an inner I~evlar section 64 and an outer Kevlar section 62.
The mortar projectile 11c is a high explosive pre-shrapnel projectile comprising a front section 53 and a rear section 54. The front section 53 may be manufactured from steel containing high explosive 55 surrounded by pre-fragmented steel particles 56 (which can be replaced by magnesium composite to produce an incendiary device) and a detonator 57. The detonator 57 can be adjusted with a pre-set timer to detonate in-flight or upon impact.
3o The rear section 54, which may also be manufactured from steel, contains liquid CO2.
This rear section also houses a magnesium-oxide composite with a soft metal failure diaphragm 58 and four stability fins 59 with copper tipped electrodes.

A laptop or hand-held computer could be used in conjunction with GPS
and a Terrain Mapping program to calculate and pinpoint accuracy, and would be advantageous for "Terrain Impaired" hidden targets.
The projectile 11c is dropped into the top of the barxel 2c of launcher 52 and falls to its base. The fins 59 of projectile 11c, equipped with copper tipped electrodes 60, strike the electrode segments 61 situated at the base of launcher 51, making an electrical circuit as the electrode segments are operably connected to battery pack 14b.
This ignites the magnesium-oxide composite (magnesium burns at 650°C), superheating the liquid COZ making a supercritical substance (highly dense gas) at very high pressure.

As projectile 11c leaves the bore of launcher 51, approximately 50% of the supercritical C02 has been utilised. The remainder now acts as the propellant, further accelerating the projectile.
The estimated projectile cycle time for launcher 51 is 4 seconds.
An ammunition box of approximately twenty projectiles 11c would also hold a spare high output battery pack 14b. One fully charged battery 14b would preferably be sufficient to expel 100 projectiles.
